Typefaces

Baskervville is a bookish transitional serif that gives the boutique-agency headings their editorial calm, the named Lato body is kept, and the two theme presets get their own sans and mono.

• BaskervvilleHeadings: headings 44px / 32px / 22px 700, -0.01em
• LatoBody: body 16px/1.6 400, captions 14px
• Atkinson HyperlegibleAccent: all-sans theme preset
• Anonymous ProFigures and code: mono-accent theme preset

Patterns

• split hero: serif headline left, large rounded monochrome photo right
• black pill primary button + text secondary
• icon mini-feature row under hero CTAs
• landing-page variant gallery in grey rounded tiles
• blog index with hero newsletter panel and two-column post cards
• tag filtering on blog
• live theme switcher driven by CSS variables
• four-column footer with social icons and CTA

States it is designed for

• Contact form: field errors, submitting, success, provider error with retry
• Subscribe: invalid email, already subscribed, success
• Blog tag filter with no matching posts: empty state with 'Clear filter'
• Image loading: fixed-ratio grey placeholder
• Theme preset not found in storage: fall back to default
• Long post titles clamp to 2 lines on cards

Who it is for

• small businesses and startups needing a site fast
• freelance web designers reusing a base theme
• content marketers who want a built-in blog

Layout

1. Header: wordmark left; text links (Home, Blog, About, Contact) and a black pill 'Get started' right; collapses to a menu button on mobile
2. Hero: two columns; left has 44px serif headline, short sans paragraph, black pill CTA + text link, and a row of five tiny icon features with captions; right has a tall rounded (24px) monochrome landscape photo
3. Landing pages section: serif heading + one-line intro; grid of grey rounded tiles each showing a preview thumbnail and a centred title; a 'Coming soon' tile with blurred preview
4. Blog index: grey rounded hero panel with serif title, one-line intro and inline email subscribe; 'Recent posts' two-column cards (image, serif title, two-line excerpt, date, tags)
5. Blog post: 720px prose column, serif headings, author and date line, tag chips, related posts
6. Contact: two columns (copy + details left, form right)
7. Footer: wordmark, social icon row and a small pill CTA left; three link columns (Landing pages, Company, Theme)
8. Floating theme switcher button bottom-right opening a panel of preset themes
9. Mobile: hero stacks with photo below text; post grid becomes single column

Palette

Editorial, calm and monochrome. Photography and serif type give it a boutique-agency feel.

As vibld’s tokens

The palette on the fifteen colour tokens vibld styles a project with, each text colour on the fill it is read on. Marked tokens are solved from the palette, because no swatch held that role at 4.5:1.

Type scale

Display

Baskervville 700 (a bookish transitional serif similar to the observed one), 44px hero, 32px section heads, 22px card titles, -0.01em tracking

Body

Lato 400 16px/1.6 (close to the observed humanist sans); captions 14px

Serif for every heading, sans for everything else. Theme presets may swap the pair (e.g. an all-sans or a mono preset).

Spacing and imagery

Comfortable: container 1120px; section padding 96px; tile gap 16px; card padding 16px. Radius 24px photos and panels, 12px tiles, pills fully rounded. Shadows: none by default (themes can add). 8px grid.

Large black-and-white landscape photography with soft rounded corners; blog uses warm lifestyle photos cropped 3:2; small line icons for the mini feature row.

Components

• SiteHeader
• SplitHero
• PillButton
• MiniFeatureRow
• LandingVariantTile
• NewsletterPanel
• PostCard
• TagChip
• ProsePost
• ContactForm
• SiteFooter
• ThemeSwitcher panel

Interactions

• Theme switcher applies a preset by swapping a data-theme attribute; choice persists in localStorage
• Tiles and post cards darken their background slightly and underline the title on hover
• Tag chips filter the blog index client-side and update the URL
• Contact and subscribe forms validate inline and show success in place
• Mobile menu slides down with focus trap and Escape to close

Data

• Post{slug, title, excerpt, cover, coverAlt, date, author, tags[], body (markdown)}
• Tag{slug, label}
• LandingVariant{slug, title, thumbnail, status (live|coming-soon)}
• ThemePreset{id, label, tokens{bg, surface, text, accent, radius, fontDisplay, fontBody}}
• ContactMessage{name, email, message}

Guardrails

Experience

• Keep one black pill CTA per section; secondary actions are text links
• Landing variants must each be real pages, not dead tiles; 'Coming soon' tiles are non-interactive
• Blog cards always show date and at least one tag
• Theme switcher must never change content or layout, only tokens
• Hero photo must support the message, not just decorate; crop consistently

Accessibility

• Every theme preset must pass AA; validate each preset's text/background pairs in CI
• Photos have meaningful alt text; decorative landscapes use empty alt
• Theme switcher is a labelled radio group inside a dialog
• Serif headings at 22px+ only; body stays sans 16px
• Input borders #7a7876 (4.4:1) keep fields visible on white

Security

• Contact form posts through a serverless function with zod validation and a honeypot
• Rate-limit contact submissions and strip HTML from messages
• Use a form or email provider via server-side secret, never in client code
• Collect only name, email and message; state the retention period on the page

Build prompt

The baseline every prompt in the catalog assumes, then this design’s own ten sections, from goal to guardrails.

Copy the baseline and build prompt

### How to use these prompts
Paste an entry's build prompt into your coding agent as the first message. Each prompt names its own stack, tokens and acceptance criteria; the rules below apply to all of them and can be prepended once per project.

### Engineering baseline
- TypeScript strict mode, no `any`, small typed components, feature folders, and one source of truth for design tokens (CSS variables consumed by Tailwind).
- Validate every input with a shared zod schema on the client and again on the server or edge function. Never trust client-side checks alone.
- Show loading, empty and error states for every async view. Surface errors in plain language with a retry, and log details to the console in development only.
- Keep secrets out of the bundle. Only publishable keys (for example a Supabase anon key) belong in client code; service-role keys, API keys and webhooks live in server or edge-function environment variables.

### Data and auth baseline (full-stack entries)
- Enable Row Level Security on every table before inserting data. Default-deny, then add owner-scoped policies (`auth.uid() = user_id`) and explicit role checks for admin views.
- Store roles in a separate table checked by a security-definer function, never in a user-editable profile field.
- Upload files to private storage buckets with size and MIME limits, and serve them through signed URLs.
- Rate-limit public endpoints (forms, auth, AI calls) and add a honeypot field or captcha to anonymous forms.
- Take payments through a hosted checkout and verify webhooks by signature. Never handle raw card data.

### Accessibility and UX baseline
- Target WCAG 2.2 AA: 4.5:1 contrast for normal text and 3:1 for large text, input borders, focus rings and meaningful icons or chart lines. Every palette in this catalog lists its verified pairs; re-check with a contrast tool after any colour change.
- Keep body text at 16px or larger with 1.5 line height, nothing below 12px, no light weights under 24px, and uppercase only for short labels.
- Give every interactive element a visible focus ring, full keyboard support, semantic landmarks, labelled form fields, and alt text on meaningful images.
- Respect `prefers-reduced-motion` for every animation. Give drag-and-drop and carousels keyboard and button alternatives.
- Build mobile-first and test at 375px, 768px and 1280px.

### Content guardrails
- Use original copy, fictional sample data and placeholder or licensed imagery. Do not reuse another product's name, logo, screenshots or marketing text.
- Label demo testimonials and metrics as samples. Collect the minimum personal data the feature needs.

### SaaS screen baseline
- Design every screen for its full set of states: first-run empty, loading skeleton, partial data, error with retry, permission-denied, and success feedback. Each entry lists the states its screen needs.
- Keep destructive actions (delete, revoke, downgrade, remove member) behind a confirmation that names the object, and prefer undo over a second dialog where the action is reversible.
- Enforce authorisation on the server for every action a screen exposes. Hiding a button is not access control; check the role again in the API or RLS policy.
- Never show secrets (API keys, tokens) in full after creation. Show them once, then mask them, and offer rotate and revoke.
- Keep the app shell (navigation, workspace switcher, account menu) consistent across screens, and preserve filters, sort and scroll position when the user navigates back.

### Goal
Build **Aspenfold**, a themeable marketing site for a small business or startup. It includes a homepage with a split hero, several landing-page variants, a blog with tags, an about page, a contact form and a small component kit. A floating theme switcher shows how the whole look changes by swapping a few CSS variables.

### Stack
Astro + TypeScript, Tailwind CSS mapped to CSS variables, content collections for posts, lucide icons, zod for form validation. The contact form posts to a serverless endpoint that forwards to a transactional email service. No client framework except small islands (menu, theme switcher, tag filter).

### Pages & layout
1. **Home**: header (wordmark; Home, Blog, About, Contact; black pill "Get started"). Split hero: serif headline ("Grow a business people remember"), two-line sans intro, pill CTA + "Read the guide" text link, a row of five small icon features with one-word captions; right column a tall 24px-radius black-and-white landscape photo. Then "Landing pages": grid of grey rounded tiles with thumbnail and title, plus a blurred "Coming soon" tile. Then a latest-posts strip and footer.
2. **Landing variants (`/landing/1`, `/landing/2`)**: alternative hero and section orders built from the same components.
3. **Blog index**: grey rounded panel with serif title, intro and inline subscribe; tag chips; two-column post cards (3:2 image, serif title, excerpt, date, tags).
4. **Post**: 720px prose, serif headings, author/date line, tag chips, related posts.
5. **About** and **Contact** (copy left, form right).
6. **Footer**: wordmark, social icons, small pill CTA; columns Landing pages, Company, Theme.
7. **Responsive**: hero stacks (text then photo); grids collapse to one column under 720px; the menu becomes a slide-down panel.

### Design system
- Colors (default theme): `--bg: #ffffff`, `--panel: #f0f0ef`, `--text: #111111`, `--text-2: #5f5d5b`, `--hairline: #d6d5d3` (decorative), `--footer-dark: #1f1d1b`, `--link: #1d4ed8`, `--input-border: #7a7876`. Buttons use `--text` as fill with white labels.
- Fonts: Baskervville 700 for headings (44/32/22px, -0.01em); Lato 400 for body at 16px/1.6; captions 14px. Presets may swap to an all-sans pairing (Atkinson Hyperlegible) or a mono accent (Anonymous Pro).
- Spacing: 8px grid; section padding 96px; container 1120px; tile gap 16px.
- Radius: `--radius-lg: 24px` (photos, panels), `--radius-md: 12px` (tiles, cards), pills 999px.
- Shadows: `--shadow: none` by default; presets may set a soft shadow.
- Motion: 150ms hover transitions; theme changes crossfade 200ms; disabled under reduced motion.
- Theme presets: Default (monochrome), Warm (cream background, terracotta accent), Night (dark background, light text). Each preset is only a token map.

### Components & interactions
SiteHeader, SplitHero, PillButton, MiniFeatureRow, LandingVariantTile, NewsletterPanel, PostCard, TagChip, ProsePost, ContactForm, SiteFooter, ThemeSwitcher. The switcher is a floating button that opens a dialog with preset radio cards; selecting one sets `data-theme` on `<html>` and stores it in localStorage (wrapped in try/catch). Tag chips filter posts client-side and write `?tag=`. Cards darken their panel on hover and underline titles.

### Data & state
Posts: `{slug, title, excerpt, cover, coverAlt, date, author, tags, body}` from markdown. `LandingVariant {slug, title, thumbnail, status}`. `ThemePreset {id, label, tokens}`. Contact: `{name, email, message}` validated by zod. Seed six invented posts (for example about pricing experiments and hiring a first designer) with royalty-free or generated imagery.

### Accessibility
Landmarks and one h1 per page. The theme dialog has a heading, radio group and Escape to close; focus returns to the trigger. Tag filters are toggle buttons with `aria-pressed`. Photos carry alt text; purely decorative ones use `alt=""`. Body text stays sans 16px; serif only at 22px+. Every preset's pairs are checked in CI.
Verified contrast: body text on white: #111111 on #ffffff = 18.88:1; secondary text on panel: #5f5d5b on #f0f0ef = 5.75:1; pill button label: #ffffff on #111111 = 18.88:1; link accent on white: #1d4ed8 on #ffffff = 6.7:1; input border on white: #7a7876 on #ffffff = 4.4:1; text on dark footer: #ffffff on #1f1d1b = 16.8:1; muted text on dark footer: #d6d5d3 on #1f1d1b = 11.46:1.

### Security
The contact endpoint validates with zod, enforces length limits, strips HTML, uses a honeypot and rate-limits by IP. Email provider keys live in server environment variables only. Subscribe uses double opt-in. No third-party trackers by default; collect only what the forms need.

### Performance & SEO
Static output with zero JS on posts. Responsive images (AVIF/WebP, width/height set), lazy below the fold. Self-host subsetted Baskervville and Lato. Per-page title, description, canonical, OG image, sitemap and RSS. Target a perfect Lighthouse score on home and posts.

### Guardrails
- Write original headlines and post content; no copied theme text.
- Use generic photography you have rights to or generated imagery.
- Theme presets change tokens only, never markup.
- Acceptance criteria:
  - [ ] All presets pass the recorded contrast pairs
  - [ ] Tag filter, subscribe and contact form work with keyboard only
  - [ ] Landing variants render from shared components
  - [ ] Theme choice persists across pages and falls back safely
  - [ ] Lighthouse 100 performance on home
